Sync gives you 5 GB of free cloud storage space when you sign up. You can earn an additional 20 GB by referring others. However, your file history and recovery are limited to 30 days.

When it comes to paid plans, Sync has two sets of plans: one for individuals and another for teams. For individuals, there’s the Solo Basic plan, which only offers 2 GB of cloud storage. It’s best for users who need secure storage for personal files and documents.

Sync also has the Solo Professional package, which bumps up the storage space on offer to 6 TB. Sync designed this plan with freelancers in mind.

Organizations can choose between the Teams Standard and Teams Unlimited packages if they want Sync storage for their team. Although the Standard plan offers 1 TB cloud storage, the sweet spot is the Unlimited package, which offers unlimited storage space.

Sync also offers an enterprise package designed for large companies with over 100 users. This plan includes a dedicated account manager and training sessions for all business users. Sync doesn’t have specific pricing for the enterprise package, so you’ll need to get in touch with customer support to get a tailor-made plan.

Does Sync have a money-back guarantee?

Sync provides a 30-day money-back guarantee on all new plan upgrades. You can upgrade your free plan to a paid plan at any time.


Features: What Does Sync Have to Offer?

Score scale 7/10

Sync has useful features to help you safely store and share files. However, its limited integrations take away some points. As such, we grade Sync a 7 out of 10 in this area.

Sync comes with several different options and features, including:

  • Secure file sharing
  • Team collaboration
  • Access files from anywhere
  • Backup and restore
  • Unlimited storage
  • Integrations

Secure file-sharing

Secure file sharing iconWith Sync, you can send and receive files without having to look over your shoulder. The app enables you to set access permissions on every file you send. This way, you can determine who can view files stored and what they can do with them.

Sync’s access control options include password protection, view-only access, email notifications, download restrictions, and expiry dates. You can also revoke access to any file anytime, even after you’ve shared it.

Team collaboration

Team collaboration iconSync enables you to create a centralized Sync folder containing your Sync files and documents. This folder can be accessed by your internal team and external partners.

You can also create folders for specific projects and set granular permissions to define the people who can access files and what they can do with them.

In addition, you can track changes and monitor your Sync folder in real-time through activity logs and notifications. Sync also allows you to brand your folders with your colors and logo to stand out. This is a handy feature to help you look professional.

Access files from anywhere

Access files from anywhere iconThanks to the Sync Folder, you can access your files from anywhere, regardless of your device. The cloud storage service has apps for most of the major operating systems, including Windows, Mac, Android, and iOS. Plus, you can access Sync through your browser using the web panel feature.

This makes Sync a good choice for working remotely from any part of the world. Even if you don’t have internet access, Sync provides offline access to files. That way, you can still do some work and then sync your files once you have an internet connection.

Backup and restore

Backup and restore, folders and cloud iconSync ensures that you never lose a file, thanks to its backup and restore feature.

Owing to its file versioning, you can roll back any file to an earlier version. This way, even if a file is corrupted or accidentally deleted, or even if your hardware fails, you can still get your file back without breaking a sweat. You can restore deleted files from up to 365 days back.

Furthermore, your Sync package includes a storage space known as Vault. You can backup files and folders you don’t want in your Sync folder there. It’s also a space-saving feature since vault files do not synchronize automatically.

Sync’s account rewind feature is also worth a mention. Similar to what pCloud offers, Sync allows you to restore your account to a previous stage. This is a handy feature if you lose a lot of files at once.

Integrations with third-party apps

Integration is not Sync’s strong suit. Compared to other cloud storage providers like Google One, Sync doesn’t integrate with a large range of apps. Thankfully, there are still a few apps you can use with Sync, namely:

  • Adobe Illustrator
  • Adobe PDF Reader
  • Adobe Photoshop
  • Microsoft Suite
  • Slack

Unlimited storage

Infinity symbol and bunch of boxes iconMost cloud storage providers cap the amount of storage space you get. For example, the maximum amount of storage space Google One and NordLocker offer is 2 TB.

However, Sync recently introduced a new plan, Teams Unlimited, which offers unlimited storage space. It’s ideal for businesses with large teams that often transfer large amounts of files.


Security: How Safe is Sync?

Score scale 8/10

Sync Cloud Storage bills itself as a secure cloud storage solution. Our testing proved that to be the case. Here is a summary of our findings:

  • Sync complies with strict regulations like PIPEDA and GDPR.
  • It logs some user data, but it doesn’t share them with any third party.
  • It implements zero-knowledge encryption.

For those reasons, Sync earns an 8 out of 10 in security.

Privacy practices

Security and privacy iconOne of Sync’s strengths is that it prioritizes user privacy. Because the company is based in Canada, it adheres to the country’s Personal Information Protection and Electronic Documents Act (PIPEDA). In brief, this law requires organizations to seek users’ consent before collecting, storing, or sharing their data.

For customers in Europe, Sync cloud storage follows the requirements spelled out by the much stricter General Data Protection Regulation (GDPR). This law mandates companies to meet several requirements, including having a data privacy officer, implementing data breach protocols, running a data management plan, and ensuring document compliance, record keeping, and auditing procedures.

In terms of data it collects on you, Sync logs your IP address and the time you access their service. However, in its privacy policy, the company states that it won’t share any user data with any third party, unless in response to a legal inquiry or order. Even then, it will notify you first.

Security and encryption

What is encryption iconSync has implemented zero-knowledge encryption on all its plans. This means that no one — not even Sync — has access to your password, encryption keys, and the information your store on Sync’s servers. This feature makes Sync a handy choice for keeping your documents and confidential files away from prying eyes.

It’s worth noting that your files are encrypted at all times, whether at rest or in transit. You can rest easy knowing that it’s highly unlikely for anyone to access and compromise your data.


Ease of Use: Is Sync Cloud Storage User-Friendly?

Score scale 9/10

In this section, we examine Sync’s usability, from installation to user experience. Here’s a summary of our observations:

  • Signing up, downloading, and installing Sync is a breeze.
  • When you install Sync on your computer, it creates a sync folder.
  • The Sync app allows you to customize the service to your taste.
  • The web panel helps you access, edit and manage your files on a browser.

Sync earns a 9 out of 10 in ease of use.

Sync.com’s website and installation process

Operating system up to date iconSync’s website is neat and well-organized. Combing through the website is a breeze, and the homepage has tabs linking to information about its pricing plans, features, and apps.

Sync has desktop and mobile apps for Windows, Mac, iOS, and Android. Unfortunately, it doesn’t have an app for Linux at the moment, though it is currently in the works. For now, you can access the Sync web app on Linux using a browser.

Setting up the Sync cloud storage desktop app is quick and easy across the board. To demonstrate that, we’ll walk through the steps of signing up, downloading, and installing the Sync app on a Windows device.

Here’s how to install Sync on your device:

  1. Go to Sync.com, and click on “Sign Up” in the top-right corner of the website. You’ll need to enter your email address and create a password.
  2. Screenshot of Sync app website, Sign up free button
  3. Click on “Resources,” then “Download.”

  6. Screenshot of Sync app, Installation wizard
  7. And that’s it! You’ve installed Sync on your device.

Once the app is installed, Sync will create a file on your computer labeled “Sync,” where all your files will be held. Any file you add to the Sync folder will be backed up automatically.

Once you’re done with the installation, you can access the Sync app on your Windows system tray at the bottom right corner of your screen. If it’s not visible there, click the white up arrow.

Sync’s usability

The Sync app is straightforward and devoid of clutter. The default view is your Sync folder/vault, which contains all your uploaded files. You can search for specific files using the search bar at the bottom of the screen.

At the upper right corner of the app, you’ll find three icons:

  • The cloud icon: Opens Sync.com’s web panel
  • The folder icon: Opens the Sync folder on your computer
  • Gear icon: Opens the settings tab

Clinking on the settings button (the gear icon) contains links to the Sync folder, the web panel, recently fetched files, events, and the support center.

The web panel allows you to view and edit your files from any web browser. It also allows you to set your sharing preferences and add users to your Sync account.

Under settings, you’ll also find the “Preferences” tab, which allows you to tweak several options, including choosing when Sync starts up, changing your password, setting upload and download speeds, and choosing folders to sync.

Customer Service: Is Sync’s Support Helpful?

Score showing 5 out of 10 on the scale

We reviewed and tested Sync’s support to see how it stacks up. Here is a snapshot of our findings:

  • Sync doesn’t have live chat, phone support, or a community forum.
  • The knowledge base is full of step-by-step instructions, tutorials, and FAQs.
  • You can fill out a form to contact a support agent, although responses might be slow.

As a result, we grade Sync a 5 out of 10 for customer service.

Knowledge base and contacting support

If you run into any challenges while using the Sync cloud storage platform, check the knowledge base to find articles, step-by-step guides, FAQs, and tutorials.

Screenshot of Sync app, help center categories

The resources are compiled under various categories, including “Accounts and Billing,” “Team Shared Folders,” “File Requests,” “Vault,” “Mobile Apps,” and “Password and Security.” This makes it easy to find the information you want.

The articles are skimmable, insightful, and actionable. Some of them contain screenshots and short videos to help you follow along.

If the knowledge base doesn’t contain the answers you’re looking for, reach out to Sync’s support team. To do that, click “Contact Support” under “Categories” in the help center.

Next, fill out the contact support form by entering your name, email, and message.

We tested this feature with a dummy inquiry. We received a response within six hours of sending the request, and the answers were detailed and helpful. We liked that the response contained links to resources that shed more light on the questions we asked.

Missing features

Sync cloud storage does not have a live chat feature or phone support, meaning that your best bet to get quick answers is to fill out the contact support form.

In addition, the service doesn’t have a community forum, which could be an excellent opportunity for learning from and interacting with other users.

We would like to see Sync add more options for contacting customer support, especially for those who subscribed to their Teams plans. Live chat, specifically, is standard in many software companies today.


Sync.com Review: Is it Worth Purchasing?

Total score review table, Sync App
Sync does not integrate with other services the way Google Drive and iCloud do, but it offers the key functions you’d want in a storage system: file syncing, collaboration, versioning, and remote access.

It’s a good choice if you want affordable cloud storage with excellent security and privacy features, including zero-knowledge encryption.

Sync is also an excellent choice for businesses thanks to its budget-friendly pricing, unlimited storage offer, and collaboration features. Its only downside is its lack of customer support options, particularly a live chat feature.

With a total score of 7.3 out of 10, we readily recommend Sync for those who need a cloud storage solution. You can download Sync by clicking the button below.
